Author's Note: 10 Questions That Science Can't Answer Yet

It's easy for modern people to look back on their ancestors with more than a little disdain. Living in caves, really? Where's your dignity, ape men? But most of us understand that 100 years from now, our grandchildren will look back at us with the same kind of mild sympathy, thinking of us as primitive and unknowing. The evolution of human science and knowledge has that kind of effect. So maybe in 20 or 50 years, this list of unanswered questions will seem quaint and naïve. It's more likely, though, that at least some these questions are going to stand the test of time.
